Dev GridControl 和chartControl、SplitterControl 简单操作

此案例是关于Dev GridControl 合chartControl 控件的显示数据，

GridControl 控件：

1.绑定IList<T> 对象，

2.实现全选，

//点击全选按钮取得方法private void checkEdit1_CheckedChanged(object sender, EventArgs e) { try { listP = gridControl1.DataSource as IList<Perf_cell_g>; for (int i = 0; i < listP.Count; i++) { Perf_cell_g p = listP[i] as Perf_cell_g; p.CHECK = checkEdit1.Checked; } gridControl1.RefreshDataSource(); } catch (Exception) { } }

3.删除选择的多行，

/// <summary> /// 删除选中行的数据 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void simpleButton2_Click(object sender, EventArgs e) { List<string> selectedRows = new List<string>(); listP = gridControl1.DataSource as IList<Perf_cell_g>; for (int i = 0; i < listP.Count; i++) { Perf_cell_g p = listP[i] as Perf_cell_g; if (p.CHECK.ToString().ToLower() == "true") { selectedRows.Add(p.CHECK.ToString()); } } if (DialogResult.OK == MessageBox.Show("确认删除此模板?", "提示", MessageBoxButtons.OKCancel, MessageBoxIcon.Warning)) { MessageBox.Show(string.Format("选中了{0}个需要删除的数据", selectedRows.Count)); } //删除选中的行 }

4.在GridControl 最下行显示某列所有数据计算总和、某列下行显示总记录数，

//设置属性 this.gridColumn2.SummaryItem.DisplayFormat = "总记录数={0}"; this.gridColumn2.SummaryItem.FieldName = "CHINA_NAME"; this.gridColumn2.SummaryItem.SummaryType = DevExpress.Data.SummaryItemType.Count;

5.某列中对于数据>3300 该列特殊颜色显示，

方法一（写方法）：/// <summary> /// 行单元格的样式 对于Ci列如果改列值大于3300 高亮显示该列 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void gridView1_RowCellStyle(object sender, DevExpress.XtraGrid.Views.Grid.RowCellStyleEventArgs e) { try { if (e.Column.FieldName != "Ci") return; string ciV = gridView1.GetListSourceRowCellValue(e.RowHandle, e.Column.FieldName).ToString(); //获取ci 列的值 if (ciV.Trim() != "") { if (Convert.ToInt32(ciV) > 3300) { DevExpress.Utils.AppearanceHelper.Apply(e.Appearance, appType1); } } } catch { } }方法二（属性设置GridView1 属性中添加）：styleFormatCondition1.Appearance.BackColor = System.Drawing.Color.FromArgb(((int)(((byte)(255)))), ((int)(((byte)(255)))), ((int)(((byte)(128))))); styleFormatCondition1.Appearance.BackColor2 = System.Drawing.Color.FromArgb(((int)(((byte)(255)))), ((int)(((byte)(255)))), ((int)(((byte)(192))))); styleFormatCondition1.Appearance.ForeColor = System.Drawing.Color.Black; styleFormatCondition1.Appearance.GradientMode = System.Drawing.Drawing2D.LinearGradientMode.Vertical; styleFormatCondition1.Appearance.Options.UseBackColor = true; styleFormatCondition1.Appearance.Options.UseForeColor = true; styleFormatCondition1.Column = this.gridColumn4; styleFormatCondition1.Condition = DevExpress.XtraGrid.FormatConditionEnum.GreaterOrEqual; styleFormatCondition1.Value1 = "3300"; this.gridView1.FormatConditions.AddRange(new DevExpress.XtraGrid.StyleFormatCondition[] { styleFormatCondition1});

6.隐藏GridControl 表最上行的英文字符

7.设置GridControl 中除了check 列之外的列不能编辑

 

chartControl 控件：

1.点击GridControl 该行某列下表显示该列的线性图形（chartControl）

2.根据GridControl 选择行某列的值，图的标题相应改变为该列的值

SplitterControl 用于分割两个控件 // // splitterControl1 // this.splitterControl1.Dock = System.Windows.Forms.DockStyle.Bottom; this.splitterControl1.Location = new System.Drawing.Point(0, 336); this.splitterControl1.Name = "splitterControl1"; this.splitterControl1.Size = new System.Drawing.Size(1028, 6); this.splitterControl1.TabIndex = 1; this.splitterControl1.TabStop = false;效果图片：
